Abstract

The tolerance of canola and wild mustard to postemergence HOE 075032 was investigated in greenhouse and field studies. In the greenhouse, the tolerance of canola to HOE 075032 applied at the 2 Ho 3-leaf stage was approximately twice the tolerance of wild mustard. In the field, HOE 075032 applied at 5 and 10 g ai/ha at the 2 to 3-leaf stage reduced wild mustard plant density and fresh weight by over 95%. Wild mustard contamination in canola seed was reduced from 45 to less than 1%. Application of HOE 075032 at 5 g/ha significantly increased canola yield and fresh weight in each year. Canola yield increases of 25, 139, and 86% were observed for the 5 g/ha treatment in 1991, 1992, and 1993, respectively. HOE 075032 could provide a postemergent alternative to the existing herbicide for wild mustard control in canola.
